This study evaluated parental anxiety and parenting practices associated with comorbid Anxiety Disorders among children with Attention Deficit/Hyperactivity Disorder. Clinic-referred families (n=143) were diagnosed using DSM criteria. Parents and children completed measures of parenting practices. Comorbid anxiety in children was significantly associated with maternal anxiety, overprotectiveness, and a lack of positive parenting. The relative odds of comorbid anxiety appeared to be especially high when all three factors were present. These findings are consistent with theory linking those three family factors to the development of anxiety in all children. Implications for adjunctive treatment of anxiety that is comorbid with ADHD are discussed.
